Re: Curly leaves
I also did what you have done, but I installed gravel, sand, redwood sawdust over a pair of 3.5" perforated drainage pipes that lead to the city's runoff sewers. This way, excess water is really going out of my yard.
If you have good drainage, then overwatering is never a problem. You don't have problems with salts either. The incomplete unfurling of leaves will only be due to very low humidity during a heat wave under intense sunlight and or excessive fertilizers. I am leaning towards the low humidity part and full sunlight, and bananas reaction is normal. Bananas are not really accustomed to desert areas like California, but we still try and achieve the unthinkable. So not surprisingly, my bananas in the shaded area have not exhibited such symptoms and they are greener as well, unlike those in full sunshine. Bananas love California sunshine if it can be toned down to 30% to 60% intensity when it the air is dry.
